Description

Method for producing an identification carrier or electronic key for electronically actuable locks

The invention relates to a method for producing an identification carrier or electronic key for electrically operated locks.

Identification carriers or electronic keys for the actuation of electrically actuable locks have become known in various designs. For example, magnetic cards have become known, on the magnetic strip, an electrical code is stored, which can be read when inserting the magnetic card in a corresponding reader, depending on the read code, the access authorization is determined and the lock is opened, if necessary. Furthermore, identification carriers or electronic keys have become known, in which the identification code stored thereon can be read out wirelessly. In particular, transponder keys that work on the basis of RFID (Radio Frequency Identification) technology should be mentioned in this context.

The structure of an RFID transponder provides in principle an antenna, an analogue circuit for receiving and transmitting (transponder) as well as a digital circuit and a permanent memory. The RFID communication between a lock and a transponder key works as follows: The reading device arranged in the lock or in the vicinity of the lock generates an electromagnetic or magnetic RF field which receives the antenna of the RFID transponder. In the antenna coil, as soon as it comes in the vicinity of the electromagnetic or magnetic field, induction current. This activates the microchip in the transponder key. Due to the induced current, a capacitor is also charged in passive transponders, which ensures lasting power supply of the chip. This assumes a built-in battery with active transponder keys. After activation of the microchip, the transponder key receives commands from the reader, whereby in response to such commands, the identification code stored in the memory is usually sent from the key to the lock.

On the other hand, it is known to provide goods, articles or security documents with electronically readable information by means of RFID transponders. WO 00/07151 A1 describes the use of RFID technology for securing securities, for example banknotes, checks, shares and the like. The output from the RFID transponder output that contains the identification information is an authentication feature and is checked to verify the authenticity of the security document. The output signal that the RFID transponder emits when the carrier frequency is coupled in contains, e.g. the individual serial number of the security document, which is also printed on the security document. To verify this two information, it is determined whether the security document is a forgery or not.

The application of a transponder to a security document is also described in EP 1134694 A1. Again, the transponder is used as a feature for detecting fakes or order of the document.

WO 03/057501 Al describes a value or security document to which an electronic circuit can be applied, wherein at least one element of the electronic

Circuit printed on the value or security document. For the production of printed conductors or other electrically conductive structures of the circuit in this case an electrically conductive ink is used. As electrically conductive printing ink, for example, is an electrically conductive polymer. Such electrically conductive polymers are known per se from the prior art. Furthermore, insulating and / or dielectric and / or highly permeable and / or piezoelectric printing inks can be used for the realization of circuit structures. From the organic semiconductor technology, the application of organic semiconductive layers, for example of conjugated polymers, such as polythiophenes, polythienylenevinylene or polyfluorene derivatives is known. The layers or printing inks are preferably applied by a printing process, such as ink jet printing process, screen printing, high pressure, gravure printing and planographic printing, already structured partially or pattern.

The use of printing methods for applying electronic circuits to security or security documents, such as banknotes, has hitherto been associated with the advantage that the electrical circuit is adapted to the mechanical flexibility of the security or security document and that the electronic circuit is adapted

Handling of the securities or security document is not affected.

The present invention now aims to provide a method for producing an identification carrier or electronic key, wherein the key obtained by the method should be particularly suitable for short-term use, for example in the context of Hotelzimmerschließanlangen suitable, with objects of any kind can be used as a key ,

To achieve this object, the inventive method is characterized essentially by the fact that an integrated circuit having at least one memory module is at least partially applied to a carrier by means of a printing method and that an identification code is stored on the memory module. Characterized in that the circuit containing the identification code is applied to a carrier by means of a printing process, can Almost any carrier can be used, this carrier by printing an integrated circuit and subsequent storage of the respective identification code becomes a key. Thus, arbitrary objects can be given the function of a key by the printing of the circuit, so that such a key is always available with appropriate choice of the carrier and does not have to be carried separately. In connection with hotel room locking systems, it is conceivable, for example, for the hotel guest to provide a personal item, such as a passport or an identification card, on which the integrated circuit is printed by means of printing methods, whereby after being loaded or stored by the printing method (eg ROM) of the identification code is the passport or the identity card to the hotel room key. Through the appropriate programming of the hotel room locking system, it can be provided that the identification code assigned to the respective hotel guest only remains valid for the duration of the stay of the guest. After expiry of the validity period, the identification code is subsequently deleted from the list of access authorizations, so that there is no need to remove the integrated circuit from the personal object of the hotel guest. Rather, the integrated circuit may remain on the personal item, with the imprinted circuit optionally being made by the hotel guest himself by removing the ink by means of suitable solvents.

According to the invention, the circuit is applied at least partially by a printing process. In this case, for example, the antenna provided for the transmission and reception of the data can be applied by means of conventional methods. Alternatively, the antenna is also applied by means of a printing method. In order to extend the durability of the applied circuit on the carrier surface, it is preferably provided that the applied circuit is covered with a protective layer, for example a foil.

Universal usability of the identification carrier which can be produced by printing the circuit is ensured, in particular, if, as is the case with a preferred embodiment, an adhesive film is selected as the carrier. The integrated circuit is thus printed on an adhesive film, the adhesive film can then be applied to any objects, which thus receive a key function. If necessary, the film can be easily detached from the object again.

As already mentioned, suitable carriers for the process according to the invention are virtually any desired articles, paper, cardboard or a plastic card being preferably selected as the carrier.

The carrier can in turn be applied to an object, in which case special circumstances of the article can be taken into account. The carrier may in this case be, for example, a planar, rigid plate which is applied to an uneven object, whereby a subject which may be difficult to print due to its unevenness can also play a key function. In this case, the carrier may possibly be adapted to the unevenness (s) of the article, so that the unevenness is compensated for after application of the carrier. The carrier may also be designed to be applied to the article while maintaining a distance from the surface of the article, which is particularly useful if the communication between the circuit printed on the carrier and the lock were disturbed by metallic surfaces of the article , The electronic circuit and the identification code stored therein may cooperate in any manner with the lock for determining the access authorization and for opening or locking the lock, wherein the combination between the electronic key and the lock for the purpose of reading the identification code both wirelessly and contact-related can be done. In a preferred manner, in this case the procedure is such that the electronic circuit is applied to form a transponder chip and that further an antenna is applied to the carrier by means of a printing process. In this way, a so-called RFID chip can be produced, so that the reading of the identification code can be carried out in a simple manner wirelessly and can be omitted in a passive embodiment of the RFID transponder, a separate power supply of the key.

In summary, the invention thus relates to the use of integrated circuits, which are made at least in part by a printing process, as an identification carrier or electronic keys for electrically operated locks.
